HC-FFT: highly configurable and efficient FFT implementation on FPGA

Abstract: FFT is one of the basic building blocks in many applications such as sensors, radars, communications. For some applications, e.g., real-time spectral monitoring and analysis, FFT needs to be "run-time configurable" so that the system is real-time. When examining the previous work on configurable real-time (FPGA-based) FFT implementations, we see that the degree of configurability is less than what is desired. In this paper, a new FFT architecture is proposed, which has a high degree of run-time configurability… Show more

“…According to the different number of channels in the structure, pipelined structures can be divided into two categories: S (Single-path) and M (Multi-path), which can be combined with DF and DC to form a variety of structures such as SDF, MDC [7] and SDC [8]. At present, there are also many parallel structures proposed based on these pipelined structures [9]- [10]. The basic algorithms used to implement pipelined FFT have different cardinalities [11]- [16].…”
